Porro prisms are most often used in pairs, forming a double Porro prism. A second prism rotated 90° with respect to the first, is placed such that light will traverse both prisms. The net effect of the prism system is a beam parallel to but displaced from its original direction, with the image rotated 180°.

The price of a product or service is defined as cost plus profit, whereas cost can be broken down further into direct cost and indirect cost.
